This is an unmarked version of Benihana's 'Geisha Mug'. I know Benihana have used many different versions of this, but they all usually have some sort of logo - so these (I've got a pair) may well be a copy used by some other Oriental-style restaurant. Dunno.

This white mug is shaped like a woman's full body, with a fan in her hand. No markings. Not as much detail as on similar Benihana marked Standing Geisha With Fan mugs.
